Zinc Plated NdFeB Ring Tube Axially Magnetized Strong Permanent Magnet
Neodymium Ring Magnet manufacturer & supplier
Rare Earth Ring Magnets, also known as neodymium ring magnets, are often used in joinery and shop-fitting as they may be recessed and screwed into position. Although not as strong as Neodymium discs, the hole in centre of the ring magnet ensures great versatility.
Neodymium rings are one of the most popular shapes of rare earth magnets. MPCO Magnetics manufactures a wide range of ring magnets in different sizes and with several different coatings such as Nickel, Zinc, Epoxy or Gold to prevent and reduce wear and corrosion.
Strong Neodymium Ring Magnets N35, N38, N42, N45, N50 & N52. Neodymium Ring Magnets are widely used in such applications as holding, motors, consumer electronics, medical, sensors and speakers. Due to the high magnetic strength of a Rare Earth Magnet, it has replaced other magnetic materials in order to make a design smaller but achieve the same result.
